Running properly again

Filed under: Orienteering and Running — Chris Curtis @ 14:15

It is very difficult for me to keep running regularly. There are lots of excuses, and they are genuine, but I suffer without that regular exercise, and without the concentrated way that being out there, on your own, pushing your physical limits brings things back to utter simplicity. I do need a programme or plan to follow: it helps to keep the excuses in perspective and raises the priority of getting out there.

I am using “getrunning” on my iPhone. A pleasant sounding, but very bossy (and encouraging), woman’s voice cuts over whatever is playing to tell me when to run and when I can rest. After a long lay-off I have gone from 6 minutes of slow running to 16 minutes of reasonable running within a half-hour framework all in four weeks. Each “step up” is hard but possible and each success makes you more determined. Ten weeks should see me back to running full 5Ks and I will then need a new programme to take me on towards 10K which I want to run for real in the autumn.

M13 again

I think this one is a keeper!
I spent a happy couple of hours reprocessing this (actually doing much less to it than I might normally do) and then calculating the colour correction to make my raw frames match a reference image from the Hubble Space telescope.
I am particularly pleased that the two populations of stars are clearly visible. The majority are old and turning gradually yellowish as they begin to use all their fuel. The “blue stragglers” are a mystery, but the latest thinking is that they might be formed where two old stars collide and merge, effectively creating one new, hot star.
